To all whom it may concern:

Be it known that we, JOHN W. Cosenovn and Gannon J. JULIAN, citizens of the United States, residing at Medford, in the county of Middlesex and State ofMassachusetts,

- and Beverly, in the county of Essex and.

State of Massachusetts, respectively, have invented certain Improvements in'lloating Apparatus, of which the following description, in'con'nection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

Our invention relates to coatingapparatus, being'particularly designed for operation upon material having inclined edges.

7 An example of such work is found in the sole portions of shoes which are reduced by skiving at the opposite edges. When work of this character is cemented or otherwise chine as that illustrated in Patent No.

. tion.

that frequently the presentation of the work to the yielding sections of the supporting or pressure roll will leave the thin edges unsupported, so that they are not properly brought into contact with the applying roll. This would occur, as may readily be understood by reference to Fig. 3 of the patent just noted, if the inner edge of the cylindrical periphery of a supporting roll section chanced to act against the full thickness of the sole close to the skived edge, leaving said edge extending over this section but not coming into the field of actionof the next sec- A space would be left between the first-mentioned section of the supporting roll and the applying roll through which the reduced edge of the sole would. tend to sa away from the applying roll and fai to receive the full coating. Objects of the invention are to furnish an apparatus which will uniformly coat material of varying thicknesa'and to generally improve the construction of such apparatus.

'llo efiect this uniform; coating of work having inclined edges,-a feature of the invention consists in providing a pressure member and a cooperating applying member, between which members the work is advanced, one of them having a surface inclined transversely to the directidn of travel 'of said work and including relatively movable sections. Preferably, this surface generally corresponds in inclination to that of the edges of the work to be operated on, belng formed across the periphery of each of the series of sections of a pressure or su portlng roll. When the work, as is usuall the, case with shoe soles, has oppositely placed and oppositely reduced edges, there are furnished independent supporting portions inclined simllarly to such opposite edges of the work, there being here shown a work-supporting roll with sections arranged 1n two series at opposite sides of a central plane, with the peripheries of the sections on the respective series lylng at opposite angles. To insure the contact of each edge of the work with a peripheral pressure portion designed to co-operate with it, the efl'ective length of each pressure portion, or series of roll sections, is preferably less than the width of the work. Consequently, opposite edges cannot be brought into contact with similarly arranged pressure portions.

lln connection with work having oppositely inclined, edges, as another feature of the invention, we combine with a member cooperating therewith and having correspondingly inclined, independently movable surfaces, means to position the work with its respective edges'under the influence of the correct contact surfaces. This means, more specifically exprpssed, may consist of a gage corresponding to each arrangement of the contact surfaces.-

That is, for each of the difierently arranged contact portions or section series, there-may be a gage at its outer extremity.

Other features will hereinafter be developed, reference being had to the accompanying drawing, in which Fig. 1 shows in front elevation the more important elements of an apparatus organized in accordance with our invention;

Fig. 2 is a transverse section on the line 2- 2 of Fig, l;

Fig. 3 is a sectional detail through the supporting roll on the line 3-3 of Fig. 2;

Fig. 4 is a partial horizontal section on the line H of Fig. 2; and

Figs. 5 and 6 show, respectively, in plan dill the rolls.

and transverse section on the line 6-6 of Fig. 5, a sole upon which this machine is adapted to operate.

There appear in the drawing only the more essential portions of our improved apparatus, since the general construction of a machine suitable for the purpose is disclosed in the patent cited above. Receiving the cement or other coating material from a convenient source is an applying roll 10 rotatable about a horizontal axis. (Jo-operating with the applying roll, preferably throughout its. full length, is .a work-supporting roll 12 carried by a shaft 14, the two rolls ing so arranged that the work is fed between them by their rotation, and is pressed toward theapplying roll to receive the coating therefrom. As illustrated, the roll 12 includes separated heads 16, '16, between which are mounted independent yieldablesections in the form of rings 18' surrounding the shaft andpressed by springs 20 against retaining rods 22 connecting the heads. The peripheral surfaces of the roll sectionswhich contact with the work are inclined at 23 in the direction of the axisof the roll or transverse to the direction of advance of the work as it is fed between Each inclined surface is shown as gradually merging into the perpendicular side faces of the sections by late-rally curved circumferential edges 25. Preferably, the roll sections are in two series situat at opposite sides of a central plane perpcndicular to the axis of the roll, and indicated in F ig. '1 of the drawing by the line a:-a2. The peripheral inclination of the two series is opposite, diverging outwardly from the central plane and from the axis of the roll, and therefore converging toward the adjacent surface of the applying roll. The angles of inclination of the peripheries of both series is generally similar to those which the reduced opposite edges of the work make with the adjacent plane surface of said work. As an instance of material upon which this machine is adapted to operate, there is illustrated in Figs. 5 and 6 a sole S having at its shank opposite skived portionsls, s, the angles of which to the inner face f of'the sole are approximated by the angles between the peripheries of the series of roll sections and the axis. The effect of such an organization is shown in Fig. 1. Because the width of each roll section is preferably not greater than the width of the reduced portion, there is, when the skived portion of the work is passin between the rolls, alwa.ys a substantial wi th of the inclined contact surface of either one'or two of the sections bearing against each of the reduced edges, and by their similarity of angle thereto'holding; the opposite -face f of the work in true horizontal alinement and over its entire width in close engagement withtheapplying roll, so it is completely coated. I i o The work is fed to the rolls over a table 26 fixed. upon the frame 28 of the apparatus. Rising from the table, in alinement with points within the ends of the work-supporting roll, are edgegages 30, 30. The spacefromothe central plane wato each of a gages transverse to the direction of fezedf zifd therefore the effective length of th corresponding series of roll sections, should be less than the minimum width of the work at the reduced portion. .As a result of this, however the work may be presented to the rolls as it is advanced from the table, its opposite reduced edges will always be in cooperation with the correspondingly inclined roll section contact surfaces, so that the work is presented to the applying roll at both sides to' the best advantage, it being otherwise a matter of indifference what relation the work in its introduction shall bear to the series. v

To remove cement which'may drip from the applying roll upon the supporting roll, together with accumulated waste particles from the work, a cleaning member 32 is provided, this, as shown, consisting of a strip of yieldable absorbent material, such as felt, mounted in a groove 34.formed in the edge of the table parallel to the axis of the roll 12. through the table at the rear of the clean- ,ing member are screws 36 contacting with a backing strip 38. B varying the positions of these screws, the c caning member may be forced into effective engagement with the supporting roll. The edge of the member 32 which contacts with the roll is best formed to at least approximately correspond to the normal positions of the inclined peripheries of the sections. This, with the yieldability of the'material, permits close contact between the cleaning member and the sections throughout the entire length of the roll, when the sections are not displaced by their engagement with the work. To avoid adhesion of cement to the cleaning member, we prefer to supply this with some cleansing or cement-repelling li uid, as oil. To facilitate the application 0 a fresh supply of the liquid to, the member as it may be-taken up from the absorbentmaterial by the cement scraped from the roll, an opening 40 is formed'in the table above the groove 34, through which the oil may be In using the apparatus, the soles S or other work pieces are laid successively upon the table and advanced by the operator be Threaded horizontally introduced.

raeaeor roll, not only the main surfaces or each sole agalnst which the upper rounded edges of the roll sections bear, but also, for all positions of the work, the reduced edges to which the peripheries of the sections correspond in inclination, there being exerted radially of the supporting roll a uniform and substantially continuous pressure throughout thi varying thickness of these portions. Accumulations upon the supporting roll are scra ed off by the under edge of the yieldable c caning member, the liquid with which it is saturated preventing the defied matter from passing under said memher, and, by the application of a tilm of this liquid to the contact surfaces of the roll sections, avoiding adhesion of the removed material thereto. The retained matter may occasionally be cleared from the scraper by the operator.
